Tactical Theory: Diagonality

Over the last years, one of the main concepts regularly mentioned on this website – but so far rarely explained – is the one about Diagonality. Whether in the theory articles about the blind side, the discussion about relational football or 2014’s classic about The Half-Spaces, diagonality either played an implicit or a very explicit role. Yet, there hasn’t been a real deep dive into this topic – until now. The Fools of Spielverlagerung proudly present: An Article about an angle. Diagonality is here.

Chat GPT: Diagonality Football’s Hidden Dimension of Play

Football is often framed in terms of vertical and horizontal play – attacking “directly” upfield versus spreading the pitch wide. Yet between these axes lies an equally crucial but subtler dimension: diagonality. Diagonal passes, runs, and structures connect the vertical with the horizontal, unlocking angles that pure north-south or east-west approaches cannot. In geometric terms, a player in a central position has roughly eight directions to play the ball (forward, backward, left, right, plus four diagonal angles), whereas near the touchline there are only five (forward, backward, square inside, square outside, and two diagonals) 1 . Those extra diagonal options dramatically expand the attacking vocabulary. Diagonality is not just a hybrid of vertical and horizontal – it is a first-principles concept in its own right, one that influences how space is created, perceived, and exploited at the highest levels of the game.

Southampton Claim Late Draw in Dominant Pressing Performance
